Every time i hit enter within my comment textfield and click submit it causes it to echo that the content is invalid.

 

Example:

 

TectField comment would be wrritten like so;

 

Some comment that i wish to hit enter

without an error.

 

<?php
$text = strip_tags(addslashes($_POST['textfield']));

if (!ctype_alnum(str_replace(" ", "", $text))){
echo "Bad content found";
}elseif (ctype_alnum(str_replace(" ", "", $text))){
echo "Good content";
}
?>

[code]<?php
$text = strip_tags(addslashes($_POST['textfield']));

if (!ctype_alnum(str_replace(" ", "", $text))){
echo "Bad content found";
}elseif (ctype_alnum(str_replace(" ", "", $text))){
echo "Good content";
}

 

change Good content to bad content found     

 

And why don't you just use If and else?

 

?>[/code]

Please think about what your posting Liam before doing so.

possibly a useless suggestion

 

try trimming, and maybe replacing windows newlines with unix newlines, or the other way round...

 

<?php
//...

$text = trim(strip_tags(addslashes($_POST['textfield'])));
$text = str_replace("\r\n", "\n", $text); // replace windows newline with unix...
